You made a really cool top from your left over hearts. sewmom has a very good idea about auditioning different ideas while it is on the wall. Take a few days to play with it and even post some of your choices and get opinions from QB.
Some one on the QB made a scalloped border from a heart pattern and it was way cool and your hearts would work well with that kind of border in that dark purple. I know there is a pattern for it. If interested I can try to locate it.
